OPERASI HITUNG
Operasi hitung campuran pada bilangan bulat
Langkah-langkah
, (Sama Kuat) => Operasi yang terletak
disebelah kiri dikerjakan terlebih dahulu.
, (Lebih Kuat daripada) , Maka
dikerjakan terlebih dahulu.
Apabila terdapat tanda kurung, Maka yang berada dalam tanda kurung harus dikerjakan terlebih dahulu.

a x 42 – 384 : 12 = 24 + (56 x 42) – (384 : 12)
= – 32
= 237 – 32
= 2344
b. 80 : ((11-7) x (-4)) = 80 : (4 x (-4))
= 80 : (-16)
= -5
c. (-8 + 5) x (36 : (6 - 9)) = -3 x (36 : (-3))
= -3 x (-12)

-15 – (-9) + (-18) – (-22) =
Menggunakan sifat distribusi, tentukan
12 x (6 + 3) =
(6 x 4) – (6 x 2) =
PEMBAHASAN
1. Hasil dari
8 + (-16) – (-25) – (-4) = = 21
-15 – (-9) + (-18) – (-22) = = -2
2. Menggunakan Sifat Distribusi
12 x (6 + 3) = (12 x 6) + (12 x 3) = 108
(6 x 4) – (6 x 2) = 6 x (4-2) = 12
